Question

f the plasma membrane of an animal cell was made entirely permeable to Na , the Na /K pump would continue to pump ions and hydrolyse ATP, but not build a Na gradient. True or False

Answer 1

Answer:

TRUE

Explanation: The Energy gradient of a Cell is the loss of energy resulting from friction provided against the free flow of materials, fluids or ions.

The plasma permeable membrane has been made entirely permeable to sodium ions so there is no resistance to the flow of sodium ions,under this circumstances no Energy gradient for sodium ions will be generated.

The Sodium-potassium pump is present in most plasma membrane its role is to regulate the movement of Sodium-potassium through the plasma membrane of a Cell.
